Smile and relax. Be yourself. Your body language reflects how you feel. Being relaxed will show you are confident and friendly. Otherwise, you may appear awkward, or worse, look like someone to avoid.
Look for something positive about her to comment on when you are ready to approach her. Be genuine with your compliments and make your conversation casual, fun and witty at the same time. You will probably catch a smile or giggle from her.
Show respect for her even as you are flirting -- that way she will not take your comments the wrong way. Don't be afraid to let her know you enjoy her company and want to get to know her.
Look her in the eyes when talking to her and smile.
Try teasing her a little bit. This is a harmless way to see if she will respond to more flirtatious behavior from you. Think of other things about her that you can compliment, such as her appearance, her dress style, her unusual purse or the color of her eyes. Try to comment in such a way that you catch her interest and also make her laugh.
Be genuinely interested in her and what she is interested in.
Have fun flirting and good luck.
- Take precaution that your flirting is not making her uncomfortable. Look for her body language or cues to see if she is taking to your flirting or if she is wishing you to back off. If she appears to enjoy it, you are doing a fine job. If not, apologize and practice some more.
